Installing Lag Shield Anchors

The installation of lag shield anchors can be done in the five steps outlined below. Lag shields are rust-proof and are often used in concrete, tile, brick cinder block, mortar and stone. Depending on the type of material and level of strength needed to secure the object, lag shield anchors came in both long and short lengths. A lag shield can be removed and unbolted after installation if necessary.

1. Drill hole of recommended diameter, into the base material equal to the length of the expansion anchor plus one half inch (1/2") or more.
2. Clean the hole of all dust and cuttings.
3. Place the expansion anchor, ribbed end first, into hole. Tap with a hammer until flush with the surface of base material.
4. Position the material to be fastened over the shield in the base material and screw in the lag screw.
5. If the lag screw begins to torque-up or tighten before the head of the lag screw mates up against the object being fastened, the shield should be driven deeper into the hole by hand hammering the head of the lag screw until flush to the object being fastened. Re-tighten the lag screw to complete the expansion of the shield and to secure the material being fastened.
